Six zones across the mainland and islands — plus the states that refuse to change their clocks.
The 50 US states span six timezones; including territories, the country covers even more. Here’s the full map in table form.
| Zone | Standard | Daylight | Major cities |
|---|---|---|---|
| Eastern (ET) | UTC-5 | UTC-4 | New York, Washington, Miami, Atlanta |
| Central (CT) | UTC-6 | UTC-5 | Chicago, Dallas, Houston, New Orleans |
| Mountain (MT) | UTC-7 | UTC-6 | Denver, Salt Lake City, Phoenix* |
| Pacific (PT) | UTC-8 | UTC-7 | Los Angeles, San Francisco, Seattle |
| Alaska (AKT) | UTC-9 | UTC-8 | Anchorage |
| Hawaii (HST) | UTC-10 | — no DST | Honolulu |
*Phoenix and most of Arizona stay on UTC-7 year-round (no DST) — effectively matching Pacific time in summer and Mountain time in winter. The Navajo Nation within Arizona does observe DST. Hawaii also never changes.
Over a dozen states straddle two zones — Indiana, Kentucky, Tennessee, Florida (the Panhandle is Central), Texas (far west is Mountain), and the Dakotas among them. Always check by city, not state.
Puerto Rico and the US Virgin Islands use Atlantic Time (UTC-4, no DST); Guam uses UTC+10; American Samoa uses UTC-11.
Coast to coast is 3 hours: 9 AM in New York is 6 AM in Los Angeles. Compare live clocks: New York · Chicago. Converting to India? Each US zone has its own gap — see the US–India planner.
The 50 states span six timezones: Eastern, Central, Mountain, Pacific, Alaska, and Hawaii. Territories add Atlantic, Chamorro, and Samoa time.
Hawaii and most of Arizona (except the Navajo Nation). US territories also skip DST.
Three hours — New York (Eastern) is ahead of Los Angeles (Pacific). 9 AM in New York is 6 AM in LA.
